My invention has reference to means for causing one moving door or the like to communicate corresponding motion to another door, so that both doors will move simulta- The invention consists in two doors connected together bya series of levers, three of which levers'have fixed pivotal points.

The invention further consists in the novel details of improvement and the combinations of parts that will be more fully hereinafter set forth and then pointed out in the claim.

Reference is to be had to the accompanying drawings, forming part hereof, wherein- Figure 1 is a vertical .cross section of a car body showing the doors and levers in the extended or open position. Fig. 2 is a similar View of the upper portion of the car, showing the doors closed; and Fig. 3 is a sectional detail View of the pivot for the levers 3*.

and supported and guided at the top in any suitable manner, and by-rails 2 at the bottom.

The lever 3 is pivoted upon the car frame at 4, and links 3 connect the ends of the lever 3 to the levers 3, which have slots 5 at their When the door 2 is moved its connected lever 3 turns on its fulcrum 7", and by actuating the adjacent-link 3 causes the central lever 3 to turn on its pivot at 4, thus operating the other link and lever on the opposite side -of the fulcrum 4, and communicating the desired motion to the opposite door 2.

Having now described my invention, what I claim is- The combination with a car frame,.having a doorway, of doors sliding against said doorway, upper and lower guides for the door, a

central lever pivoted on the frame above the doorway to swing in the plane of the door or parallel thereto, levers pivotally connected to the frame and doors,one of said pivots being slotted, and links connecting said levers and reciprocating parallel to the plane of the doors, substantially'as described.
